You may be able to switch on again the 12 V power supply for a short time
under certain circumstances. In this case you must switch on the 12 V main
switch on the DT/LT ... control and switch panel.
However, you cannot switch the 12 V power supply back on if the battery
voltage remains below 11.0 V.
Fully charge up the living area battery as soon as possible. For more infor-
mation, see the “Battery voltages” description in the associated DT/LT ...
control and switch panel instruction manual.
When using a DT/LT ... control and switch panel: approx. 20 mA;
12.6 V battery voltage after being disconnected from the mains for 10 min-
utes; battery isolation is not activated; control and switch panel illumination
and main switch are switched off.

Additional functions
This relay supplies the AES/compressor refrigerator with power from the
starter battery when the vehicle engine is running and the D+ connection is
live. An AES/compressor refrigerator is powered by the living area battery
when the vehicle engine is switched off.
This feature provides an automatic trickle charge for the starter battery up to
a 6 A maximum when the 230 V mains is connected to the Electroblock.
The “Step” output is protected with a self-resetting fuse.
If there is a fault, e.g. overcurrent, the self-resetting fuse will disconnect the
relevant circuit.
This fuse resets automatically approx. 1 minute after the fault has been rec-
tified.
The circuit is protected with a 15 A fuse.
Maximum permitted charging current 14 A, protected by a 15 A fuse
Either the living area battery or the living area battery and the starter battery
will be charged, depending on the type of the solar charger being used.
